Title: High speed signal circuit
Inventor: TACHIBANA HIDEYUKI
IPC: G06F13/36
Filed: 2001-03-06
Abstract: PROBLEM TO BE SOLVED: To make it unnecessary to facilitate any measures to a radiation noise from board wiring by maintaining the operating frequency of a synchronizing bus at a high speed by distributing a low speed synchronizing signal. SOLUTION: When completing preparation for oscillating internal clocks, internal clock generating circuits 11, 12, and 13 of respective LSI 2, 3, and 4 respectively transmit oscillation preparation completion signals CLK- EN 1, 2, and 3 to a clock synchronizing signal generating circuit 14. Then, the clock synchronizing signal generating circuit 14 transmits low speed clock synchronizing signals SYNC- PULSE to each LSI 2, 3, and 4. Thus, the internal clock generating circuits in the respective LSI 2, 3, and 4 respectively generate high speed bus clock signals CLK 1, 2, and 3 by multiplying the signals of crystal oscillators 8, 9, and 10 synchronously with the clock synchronizing signals SYNC- PULSE, and transmit them to a common synchronizing bus 1.  Therefore, the operating frequency of the synchronizing bus 1 to which the LSI 2, 3, and 4 are connected can be maintained at a high speed as it is, and the clock synchronizing signal SYNC- PULSE running through a signal line can be transmitted at a low speed so that it is possible to reduce any radiation noise from a board.

Title: Lining structure for internal surface of water way
Inventor: MIYAZAKI TORU
IPC: E02B5/02
Filed: 2001-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a lining structure for an internal surface of a water way, which cuts costs in repairing the water way, and minimizes reduction of the sectional area of the water way. SOLUTION: According to the lining structure, a lining FRPM plate 3 is fastened to the internal surface W' of the existing water way W via a sheet member 10 by means of anchors 2. Front and rear surfaces of the sheet member have bumps and dips 11a which form channels 13. The sheet member functions as a shielding wall to block leakage from the side of the water way W to the other side of the sheet member, and to block sump water from the side of a concrete wall H to the other side of the sheet member, whereby the leakage and sump water flow downstream along the channels 13. The water way W has reservoir portions for the leakage and sump water which are arranged at longitudinally suitable intervals, for introducing the leakage and sump water to the water way W, or discharging the same out of the concrete wall H.  On this occasion, sand, etc., are inhibited from infiltrating into the channels 13 by a filter 12, to thereby prevent the channels 13 from being blocked. The sectional area of the water way is reduced only by the thickness of the FRPM plate and the sheet member, and by virtue of the hydraulic property of the FRPM plate, flowing volume in the water way is increased. Further, reinforcement of anchor portions and the FRPM plate is dispensed with, which leads to reduction in cost of the lining structure.

Title: Shooting counter, live shooting data reader and shooting counter for firearm
Inventor: MORIKI MASANARI
IPC: G01P15/00
Filed: 2001-03-14
Abstract: PROBLEM TO BE SOLVED: To correctly count the number of live shoots by discriminating live shooting from a firearm. SOLUTION: A shooting discriminating device discriminates the live shooting from an acceleration signal obtained from an acceleration sensor by detecting an acceleration (shooting impact signal) accompanying the shooting of the firearm equipped with the acceleration sensor. A memory unit stores the live shooting signal discriminated by the shooting discriminating device and a time signal from a clock. A display of a shooting data reader reads out data stored in the memory secured on the firearm, i.e., the live shooting signal or a shooting time signal together with the former signal, and displays the contents of them.  A constitution may be employed wherein the memory unit directly stores the acceleration signal from the acceleration sensor, and the live shoot is discriminated in a shooting data discriminating device by using the acceleration signal thus read out from the memory unit to display the result.

IPC: H01L21/027
Filed: 2001-03-22
Abstract: PROBLEM TO BE SOLVED: To provide a toroidal deflection system which generates little heat, even if a large current flows. SOLUTION: Coils 2 are formed on both sides of a plate formed of an insulator, such as quartz. The coil is so formed that the thickness is thin on the left side of the figure and becomes thicker toward the right side. The left side is on the center side of the deflection system, and the right side is positioned outside the deflection system. Figure. (b) shows the toroidal deflection system fitted with vanes from the view of a direction along the optical axis. Each vane is fitted to a cylindrical frame body 3, but the spacing is narrow near the frame body and wider toward the outside, as shown in the Figure. Consequently, even if the thickness of the coil 2 at a part corresponding to the outside is thickened as shown in Fig. (a), there will be no occurrence of a state such that the coils 2 come in contact with each other to cause short circuit.  The electrical resistance of the coil as a whole can thereby be reduced.
